Hi Dan, I just got back from vacation and saw your posting about Gri. I've added a reference to it in the netCDF utilities document: http://www.unidata.ucar.edu/packages/netcdf/utilities.html Please let me know if this needs corrections or additions. Thanks. -- Russ Rew UCAR Unidata Program address@hidden P.O. Box 3000 http://www.unidata.ucar.edu/ Boulder, CO 80307-3000
